You haven't included the jarfile containing the Oracle JDBC Driver on the classpath.

Class.forName("oracle:jdbc:driver:OracleDriver"); There is no class which goes by the name of oracle:jdbc:driver:OracleDriver . Replace those : with . and you should be fine provided you have included the classes12.jar or some other thin oracle driver in your classpath. I don't accept change; I don't deserve to live.
Ha. ;-)
Din't really look at the class name. These classpath questions (at least because of other forums) have simply become knee-jerk reactions. ;-)
